NURS 6501 Exam 2 | NURS 6501 Advanced
Pathophysiology | Actual Q&A with Rationale (NURS
6501 Exam 2) | Walden
Section A: Multiple Choice (30 questions)
Q1. Which cardiac rhythm is most associated with risk of stroke?
• A. Sinus tachycardia
• B. Atrial fibrillation ✅
• C. Ventricular tachycardia
• D. Sinus bradycardia
Rationale: AF causes atrial stasis → thrombus formation → embolic stroke risk.
Q2. Which valve disorder produces a “mid-systolic click”?
• A. Aortic stenosis
• B. Mitral valve prolapse ✅
• C. Tricuspid regurgitation
• D. Pulmonic stenosis
Rationale: Mitral valve prolapse is classically associated with a mid-systolic
click.
Q3. Which respiratory condition is characterized by loss of elastic recoil?
, • A. Asthma
• B. Emphysema ✅
• C. Chronic bronchitis
• D. Pulmonary fibrosis
Rationale: Emphysema involves alveolar wall destruction → loss of elastic recoil →
air trapping.
Q4. Which renal condition is most associated with “crescentic glomerulonephritis”?
• A. Minimal change disease
• B. Rapidly progressive glomerulonephritis ✅
• C. Nephrotic syndrome
• D. Pyelonephritis
Rationale: RPGN shows crescent-shaped lesions in glomeruli.
Q5. Which endocrine disorder is linked to “moon face” and “buffalo hump”?
• A. Addison’s disease
• B. Cushing’s syndrome ✅
• C. Graves’ disease
• D. Hypothyroidism
, Rationale: Excess cortisol in Cushing’s causes characteristic fat redistribution.
Q6. Which cardiac biomarker rises earliest after myocardial infarction?
• A. Troponin I
• B. CK-MB ✅
• C. LDH
• D. BNP
Rationale: CK-MB rises within 3–6 hours; troponin is more specific but rises slightly
later.
Q7. Which respiratory condition is associated with “pink puffers”?
• A. Chronic bronchitis
• B. Emphysema ✅
• C. Asthma
• D. ARDS
Rationale: Emphysema patients hyperventilate to maintain oxygenation, appearing
pink.
Q8. Which renal disorder is characterized by hematuria, hypertension, and mild
proteinuria?
• A. Nephrotic syndrome
